This Panasonic ECW-FE2W225J is a high-performance film capacitor which features a dielectric of polypropylene film, with a voltage rating of 450VDC, a capacitance of 2.2uF, a low SPD (Surge Pulse Durability) rating of 5%, and a lead spacing of 15mm. It is designed to operate in high density circuits, and it has good resistance to high temperatures, voltage transients, and thermal shock. Its symmetrical properties make it suitable for across-the-line and line-to-ground applications. It is suitable for switching mode power supplies, ultra-high-speed circuits, and other high-frequency applications.
